Tires with less than 1/16" (1.6 mm) tread have very poor grip in rain or snow.
To improve tire economy:
Maintain correct tire pressure. See  the tire pressure label  on the inside of the fuel filler  door.
Drive smoothly:  avoid fast  starts, hard braking and  tire screeching.
Tire wear  increases with speed.
Correct front  wheel alignment is very important.
Unbalanced wheels impair tire economy and  driving comfort.
Volvo does not recommend rotating the tires. However, if tires are rotated, they must  be  kept on the same side of the
car so that they revolve in the same direction as before rotation.
Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a  tendency to distort
slightly,  forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however,  disappear when the tire warms up. The degree to which  flat spots form  depends on the type of cord
used in the tire. Remember that, in cold weather, it takes longer for the tire to warm up and  consequently longer for the
flat spot to disappear.
CAUTION:  The car must  not be  driven with wheels of different  dimensions/specifications or with a  spare tire other
than the one  that came with the car. The use of different  size wheels can seriously damage your car's transmission or
driveline. 
pg. 109 Wheels and tires
Snow chains
Snow chains can be  used on your Volvo with the following restrictions:
Snow chains should be  installed on front  wheels only. Use only Volvo approved snow chains.
Special  snow chains must  be  mounted on 215/55 R16. Consult your Volvo retailer.
If accessory,  aftermarket or "custom" tires and  wheels are installed and  are of a  size different  than the original tires
and  wheels, chains in some cases CANNOT be  used. Sufficient  clearances between chains and  brakes, suspension and
body components must  be  maintained.  Snow chains cannot be  used on 17" wheels.
Some strap -on type chains will interfere  with brake components and  therefore CANNOT be  used.
All Wheel Drive models: Snow chains should only be  installed on the front  wheels. Only chains adapted for AWD
models should be  used.
Consult your Volvo retailer for additional snow chain information.
CAUTION:
Check local  regulations  regarding the use of snow chains before installing.
Always follow the chain manufacturer's installation  instructions carefully. Install chains as tightly as possible and
retighten periodically.
Never  exceed the chain manufacturer's specified maximum speed limit. In no case should you exceed 31 mph (50
km/h).
Avoid bumps, holes or sharp turns when driving with snow chains.
Vehicle handling can be  adversely affected when driving with chains. Avoid fast  maneuvering and  hard braking.
